SUMMARY

An example of an embodiment of environment 200 of FIG. 3 in use may include determining whether the plurality of digital images 210 covers the entire region of interest 202 of the surface 201, or whether there are any possible non-imaged portions of the region of interest that are not covered by the plurality of digital images. This may be useful when a surface has been imaged from several different locations rather than imaged from a relatively fixed or known location such as by satellite or aerial photography. Examples of imaging a surface from several different locations may include examining a surface of an object for perceivable defects, such as missing protective tiles on a spacecraft, or when examining the skin of a person or the surface of an internal organ of a person for diseases, conditions, or changes over time. It is anticipated that a person or machine examining a surface would like to know whether the plurality of digital images covers the entire region of interest of the surface, or whether there are possible non-imaged portions of the region of interest. It is further anticipated that a person or machine examining such a surface would like to know where any possible non-imaged portions of the region of interest are located so that the examination may be adjusted for that fact, or so that additional digital images of possible non-imaged portions of the region of interest may be acquired.

This example of the environment 200 in use includes, without limitation, an embodiment of the system 220 in use. In this example, the system includes an image receiver circuit 222 configured to receive the plurality of digital images 210. The plurality of digital images each includes a respective portion of the region of interest 202 of the surface 201. See FIG. 6. For example, the surface may include the skin of a person's back, or the lining of a person's stomach. To lay the ground work for determining whether there is possible non-imaged portion 218 of the region of interest of the surface in the plurality of digital images, the system finds at least one respective perceivable feature located anywhere in the field of view for each of the plurality of digital images, including the border regions of the digital images. To this end, the system includes a feature-detection circuit 224 configured to extract at least one perceivable feature included in each digital image of the plurality of digital images. For example, where the surface is the skin, an extracted perceivable feature may include a mole, a wrinkle, a fold, a human-vision perceivable discontinuity, a hair pattern, or a vein. The system includes a border region detection circuit 226 configured to detect a border region segment of a digital image. The dimensions of the border region segment may be selected for example as is appropriate for the resolution of digital images included in the plurality of digital images and the processing power of the system.

In this example of the system 220 in use, the system looks to see if there is a common perceivable feature included in both a border region segment of a selected digital image and in another digital image of the plurality of digital images. If there is no common perceivable feature, the system reports a possible non-imaged portion of the region of interest. For example, see FIGS. 5 and 6. In this regard, a feature-matching circuit 228 of the system looks for a common perceivable feature in both a border region segment of a selected digital image and anywhere in the field of view of another digital image of the plurality of digital images. The system accomplishes this by determining if a substantial correspondence exists between (x) a perceivable feature included in a border region segment of the selected digital image of the plurality of digital images and (y) at least one respective perceivable feature included in each digital image of the plurality of digital images other than the selected digital image. For example, the feature matching circuit may output a “0” if no substantial correspondence is found, and output a “1” if a substantial correspondence is found. In an embodiment, the system proceeds around the several border regions of the selected digital image and similarly determine a substantial correspondence for each respective feature included in the several border regions with respect to each digital image of the plurality of digital images other than the selected digital image. The system includes a data collection circuit 232 configured to gather the determined substantial correspondence in the form of “1” and “0” for the perceivable feature included in the border region segment of the selected digital image.

In this example of the system 220 in use, the system includes a reporting circuit 236 configured to output informational data indicative of a possible non-imaged portion of the region of interest adjacent to the selected digital image. The informational data is responsive to an absence of a determined substantial correspondence (all 0's) between the perceivable feature included in the border region segment of the selected digital image and at least one respective perceivable feature included in each digital image of the plurality of digital images other than the selected digital image. For example, the system in generating the informational data treats a determination of an absence of substantial correspondence (all 0's) for the perceivable feature of the border region segment of the selected digital image as an indication that there likely is no border region overlap with any other feature of the remaining digital images and outputs that there is a possible adjacent non-imaged portion. For example, the system in generating the informational data treats a determination of a substantial correspondence (at least a single 1) for the perceivable feature of the border region segment of the selected digital image as an indication that there likely is a possible border region overlap with at least one detected border region feature of the remaining digital images, concludes the adjacent portion is likely imaged, and does not output that there is a possible adjacent non-imaged portion.

For example, and without limitation, an embodiment of the subject matter described herein includes a system. In this embodiment, the system includes a feature-detection circuit configured to extract at least one respective perceivable feature included in each digital image of a plurality of digital images. The each digital image of the plurality of digital images includes a respective portion of a region of interest of a surface. The system includes a feature-matching circuit configured to determine a substantial correspondence between (x) an extracted perceivable feature included in a border region segment of a selected digital image of the plurality of digital images and (y) an extracted at least one respective perceivable feature included in the each digital image of the plurality of digital images other than the selected digital image. The system includes a data collection circuit configured to gather the determined substantial correspondences for the extracted perceivable feature included in the border region segment of the selected digital image. The system includes a reporting circuit configured to output informational data indicative of a possible non-imaged portion of the region of interest of the surface. The informational data is responsive to an absence of a determined substantial correspondence between the extracted perceivable feature included in the border region segment of the selected digital image and the extracted at least one respective perceivable feature included in the each digital image of the plurality of digital images other than the selected digital image.

In an embodiment, the system includes an overlap-analysis circuit configured to generate data indicative of a border region-overlap status of the selected digital image. The data is generated at least partially in response to the determined substantial correspondence between the extracted perceivable feature included in the border region segment of the selected digital image and the extracted at least one respective perceivable feature included in the each digital image of the plurality of digital images other than the selected digital image. In an embodiment, the system includes computer-readable media configured to maintain the informational data. In an embodiment, the system includes a communication device configured to provide a notification at least partially based on the informational data to at least one of a human, computer, or system.

For example, and without limitation, an embodiment of the subject matter described herein includes a method implemented in a computing device. In this embodiment, the method includes extracting at least one respective perceivable feature included in each digital image of a plurality of digital images. The each digital image of the plurality of digital images includes a respective portion of a region of interest of a surface. The method includes determining a substantial correspondence between (x) an extracted perceivable feature included in a border region segment of a selected digital image of the plurality of digital images and (y) an extracted at least one respective perceivable feature included in each digital image of the plurality of digital images other than the selected digital image. The method includes gathering the determined substantial correspondence for the extracted perceivable feature included in the border region segment of the selected digital image. The method includes outputting informational data indicative of a possible non-imaged portion of the region of interest of the surface. The informational data is responsive to an absence of a determined substantial correspondence between the extracted perceivable feature included in the border region segment of the selected digital image and the extracted at least one respective perceivable feature included in the each digital image of the plurality of digital images other than the selected digital image.

In an embodiment, the method includes iteratively designating a next digital image from the plurality of digital images as the selected digital image until each digital image of the plurality of digital images has been designated, and initiating a processing of each of the iteratively designated next digital images. In an embodiment, the method includes displaying the informational data. In an embodiment, the method includes maintaining the informational data in computer-readable storage media. In an embodiment, the method includes providing a notification at least partially based on the informational data to at least one of a human, computer, or system.

DETAILED DESCRIPTION

In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrated embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented here.

Those having skill in the art will recognize that the state of the art has progressed to the point where there is little distinction left between hardware, software, and/or firmware implementations of aspects of systems; the use of hardware, software, and/or firmware is generally (but not always, in that in certain contexts the choice between hardware and software can become significant) a design choice representing cost vs. efficiency tradeoffs. Those having skill in the art will appreciate that there are various vehicles by which processes and/or systems and/or other technologies described herein can be effected (e.g., hardware, software, and/or firmware), and that the preferred vehicle will vary with the context in which the processes and/or systems and/or other technologies are deployed. For example, if an implementer determines that speed and accuracy are paramount, the implementer may opt for a mainly hardware and/or firmware vehicle; alternatively, if flexibility is paramount, the implementer may opt for a mainly software implementation; or, yet again alternatively, the implementer may opt for some combination of hardware, software, and/or firmware. Hence, there are several possible vehicles by which the processes and/or devices and/or other technologies described herein may be effected, none of which is inherently superior to the other in that any vehicle to be utilized is a choice dependent upon the context in which the vehicle will be deployed and the specific concerns (e.g., speed, flexibility, or predictability) of the implementer, any of which may vary. Those skilled in the art will recognize that optical aspects of implementations will typically employ optically-oriented hardware, software, and or firmware.

In some implementations described herein, logic and similar implementations may include software or other control structures suitable to operation. Electronic circuitry, for example, may manifest one or more paths of electrical current constructed and arranged to implement various logic functions as described herein. In some implementations, one or more media are configured to bear a device-detectable implementation if such media hold or transmit a special-purpose device instruction set operable to perform as described herein. In some variants, for example, this may manifest as an update or other modification of existing software or firmware, or of gate arrays or other programmable hardware, such as by performing a reception of or a transmission of one or more instructions in relation to one or more operations described herein. Alternatively or additionally, in some variants, an implementation may include special-purpose hardware, software, firmware components, and/or general-purpose components executing or otherwise invoking special-purpose components. Specifications or other implementations may be transmitted by one or more instances of tangible transmission media as described herein, optionally by packet transmission or otherwise by passing through distributed media at various times.

Alternatively or additionally, implementations may include executing a special-purpose instruction sequence or otherwise invoking circuitry for enabling, triggering, coordinating, requesting, or otherwise causing one or more occurrences of any functional operations described below. In some variants, operational or other logical descriptions herein may be expressed directly as source code and compiled or otherwise invoked as an executable instruction sequence. In some contexts, for example, C++ or other code sequences can be compiled directly or otherwise implemented in high-level descriptor languages (e.g., a logic-synthesizable language, a hardware description language, a hardware design simulation, and/or other such similar mode(s) of expression). Alternatively or additionally, some or all of the logical expression may be manifested as a Verilog-type hardware description or other circuitry model before physical implementation in hardware, especially for basic operations or timing-critical applications. Those skilled in the art will recognize how to obtain, configure, and optimize suitable transmission or computational elements, material supplies, actuators, or other common structures in light of these teachings.

A data processing system may be implemented utilizing suitable commercially available components, such as those typically found in data computing/communication and/or network computing/communication systems.

FIGS. 1 and 2 provide respective general descriptions of several environments in which implementations may be implemented. FIG. 1 is generally directed toward a thin computing environment 19 having a thin computing device 20, and FIG. 2 is generally directed toward a general purpose computing environment 100 having general purpose computing device 110. However, as prices of computer components drop and as capacity and speeds increase, there is not always a bright line between a thin computing device and a general purpose computing device. Further, there is a continuous stream of new ideas and applications for environments benefited by use of computing power. As a result, nothing should be construed to limit disclosed subject matter herein to a specific computing environment unless limited by express language.

FIG. 1 and the following discussion are intended to provide a brief, general description of a thin computing environment 19 in which embodiments may be implemented. FIG. 1 illustrates an example system that includes a thin computing device 20, which may be included or embedded in an electronic device that also includes a device functional element 50. For example, the electronic device may include any item having electrical or electronic components playing a role in a functionality of the item, such as for example, a refrigerator, a car, a digital image acquisition device, a camera, a cable modem, a printer an ultrasound device, an x-ray machine, a non-invasive imaging device, or an airplane. For example, the electronic device may include any item that interfaces with or controls a functional element of the item. In another example, the thin computing device may be included in an implantable medical apparatus or device. In a further example, the thin computing device may be operable to communicate with an implantable or implanted medical apparatus. For example, a thin computing device may include a computing device having limited resources or limited processing capability, such as a limited resource computing device, a wireless communication device, a mobile wireless communication device, a smart phone, an electronic pen, a handheld electronic writing device, a scanner, a cell phone, a smart phone (such as an Android® or iPhone® based device), a tablet device (such as an iPad®) or a Blackberry® device. For example, a thin computing device may include a thin client device or a mobile thin client device, such as a smart phone, tablet, notebook, or desktop hardware configured to function in a virtualized environment.

The thin computing device 20 includes a processing unit 21, a system memory 22, and a system bus 23 that couples various system components including the system memory 22 to the processing unit 21. The system bus 23 may be any of several types of bus structures including a memory bus or memory controller, a peripheral bus, and a local bus using any of a variety of bus architectures. The system memory includes read-only memory (ROM) 24 and random access memory (RAM) 25. A basic input/output system (BIOS) 26, containing the basic routines that help to transfer information between sub-components within the thin computing device 20, such as during start-up, is stored in the ROM 24. A number of program modules may be stored in the ROM 24 or RAM 25, including an operating system 28, one or more application programs 29, other program modules 30 and program data 31.

A user may enter commands and information into the computing device 20 through one or more input interfaces. An input interface may include a touch-sensitive display, or one or more switches or buttons with suitable input detection circuitry. A touch-sensitive display is illustrated as a display 32 and screen input detector 33. One or more switches or buttons are illustrated as hardware buttons 44 connected to the system via a hardware button interface 45. The output circuitry of the touch-sensitive display 32 is connected to the system bus 23 via a video driver 37. Other input devices may include a microphone 34 connected through a suitable audio interface 35, or a physical hardware keyboard (not shown). Output devices may include the display 32, or a projector display 36.

In addition to the display 32, the computing device 20 may include other peripheral output devices, such as at least one speaker 38. Other external input or output devices 39, such as a joystick, game pad, satellite dish, scanner or the like may be connected to the processing unit 21 through a USB port 40 and USB port interface 41, to the system bus 23. Alternatively, the other external input and output devices 39 may be connected by other interfaces, such as a parallel port, game port or other port. The computing device 20 may further include or be capable of connecting to a flash card memory (not shown) through an appropriate connection port (not shown). The computing device 20 may further include or be capable of connecting with a network through a network port 42 and network interface 43, and through wireless port 46 and corresponding wireless interface 47 may be provided to facilitate communication with other peripheral devices, including other computers, printers, and so on (not shown). It will be appreciated that the various components and connections shown are examples and other components and means of establishing communication links may be used.

The computing device 20 may be primarily designed to include a user interface. The user interface may include a character, a key-based, or another user data input via the touch sensitive display 32. The user interface may include using a stylus (not shown). Moreover, the user interface is not limited to an actual touch-sensitive panel arranged for directly receiving input, but may alternatively or in addition respond to another input device such as the microphone 34. For example, spoken words may be received at the microphone 34 and recognized. Alternatively, the computing device 20 may be designed to include a user interface having a physical keyboard (not shown).

The device functional elements 50 are typically application specific and related to a function of the electronic device, and are coupled with the system bus 23 through an interface (not shown). The functional elements may typically perform a single well-defined task with little or no user configuration or setup, such as a refrigerator keeping food cold, a cell phone connecting with an appropriate tower and transceiving voice or data information, a camera capturing and saving an image, or communicating with an implantable medical apparatus.

In certain instances, one or more elements of the thin computing device 20 may be deemed not necessary and omitted. In other instances, one or more other elements may be deemed necessary and added to the thin computing device.

FIG. 2 and the following discussion are intended to provide a brief, general description of an environment in which embodiments may be implemented. FIG. 2 illustrates an example embodiment of a general-purpose computing system in which embodiments may be implemented, shown as a computing system environment 100. Components of the computing system environment 100 may include, but are not limited to, a general purpose computing device 110 having a processor 120, a system memory 130, and a system bus 121 that couples various system components including the system memory to the processor 120. The system bus 121 may be any of several types of bus structures including a memory bus or memory controller, a peripheral bus, and a local bus using any of a variety of bus architectures. By way of example, and not limitation, such architectures include Industry Standard Architecture (ISA) bus, Micro Channel Architecture (MCA) bus, Enhanced ISA (EISA) bus, Video Electronics Standards Association (VESA) local bus, and Peripheral Component Interconnect (PCI) bus, also known as Mezzanine bus.

The computing system environment 100 typically includes a variety of computer-readable media products. Computer-readable media may include any media that can be accessed by the computing device 110 and include both volatile and nonvolatile media, removable and non-removable media. By way of example, and not of limitation, computer-readable media may include computer storage media. By way of further example, and not of limitation, computer-readable media may include a communication media.

Computer storage media includes volatile and nonvolatile, removable and non-removable media implemented in any method or technology for storage of information such as computer-readable instructions, data structures, program modules, or other data. Computer storage media includes, but is not limited to, random-access memory (RAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), flash memory, or other memory technology, CD-ROM, digital versatile disks (DVD), or other optical disk storage, magnetic cassettes, magnetic tape, magnetic disk storage, or other magnetic storage devices, or any other medium which can be used to store the desired information and which can be accessed by the computing device 110. In a further embodiment, a computer storage media may include a group of computer storage media devices. In another embodiment, a computer storage media may include an information store. In another embodiment, an information store may include a quantum memory, a photonic quantum memory, or atomic quantum memory. Combinations of any of the above may also be included within the scope of computer-readable media.

Communication media may typically embody computer-readable instructions, data structures, program modules, or other data in a modulated data signal such as a carrier wave or other transport mechanism and include any information delivery media. The term “modulated data signal” means a signal that has one or more of its characteristics set or changed in such a manner as to encode information in the signal. By way of example, and not limitation, communications media may include wired media, such as a wired network and a direct-wired connection, and wireless media such as acoustic, RF, optical, and infrared media.

The system memory 130 includes computer storage media in the form of volatile and nonvolatile memory such as ROM 131 and RAM 132. A RAM may include at least one of a DRAM, an EDO DRAM, a SDRAM, a RDRAM, a VRAM, or a DDR DRAM. A basic input/output system (BIOS) 133, containing the basic routines that help to transfer information between elements within the computing device 110, such as during start-up, is typically stored in ROM 131. RAM 132 typically contains data and program modules that are immediately accessible to or presently being operated on by the processor 120. By way of example, and not limitation, FIG. 2 illustrates an operating system 134, application programs 135, other program modules 136, and program data 137. Often, the operating system 134 offers services to applications programs 135 by way of one or more application programming interfaces (APIs) (not shown). Because the operating system 134 incorporates these services, developers of applications programs 135 need not redevelop code to use the services. Examples of APIs provided by operating systems such as Microsoft's “WINDOWS” ® are well known in the art.

The computing device 110 may also include other removable/non-removable, volatile/nonvolatile computer storage media products. By way of example only, FIG. 2 illustrates a non-removable non-volatile memory interface (hard disk interface) 140 that reads from and writes for example to non-removable, non-volatile magnetic media. FIG. 2 also illustrates a removable non-volatile memory interface 150 that, for example, is coupled to a magnetic disk drive 151 that reads from and writes to a removable, non-volatile magnetic disk 152, or is coupled to an optical disk drive 155 that reads from and writes to a removable, non-volatile optical disk 156, such as a CD ROM. Other removable/nonremovable, volatile/non-volatile computer storage media that can be used in the example operating environment include, but are not limited to, magnetic tape cassettes, memory cards, flash memory cards, DVDs, digital video tape, solid state RAM, and solid state ROM. The hard disk drive 141 is typically connected to the system bus 121 through a non-removable memory interface, such as the interface 140, and magnetic disk drive 151 and optical disk drive 155 are typically connected to the system bus 121 by a removable non-volatile memory interface, such as interface 150.

The drives and their associated computer storage media discussed above and illustrated in FIG. 2 provide storage of computer-readable instructions, data structures, program modules, and other data for the computing device 110. In FIG. 2, for example, hard disk drive 141 is illustrated as storing an operating system 144, application programs 145, other program modules 146, and program data 147. Note that these components can either be the same as or different from the operating system 134, application programs 135, other program modules 136, and program data 137. The operating system 144, application programs 145, other program modules 146, and program data 147 are given different numbers here to illustrate that, at a minimum, they are different copies.

A user may enter commands and information into the computing device 110 through input devices such as a microphone 163, keyboard 162, and pointing device 161, commonly referred to as a mouse, trackball, or touch pad. Other input devices (not shown) may include at least one of a touch sensitive display, joystick, game pad, satellite dish, and scanner. These and other input devices are often connected to the processor 120 through a user input interface 160 that is coupled to the system bus, but may be connected by other interface and bus structures, such as a parallel port, game port, or a universal serial bus (USB).

A display 191, such as a monitor or other type of display device or surface may be connected to the system bus 121 via an interface, such as a video interface 190. A projector display engine 192 that includes a projecting element may be coupled to the system bus. In addition to the display, the computing device 110 may also include other peripheral output devices such as speakers 197 and printer 196, which may be connected through an output peripheral interface 195.

The computing system environment 100 may operate in a networked environment using logical connections to one or more remote computers, such as a remote computer 180. The remote computer 180 may be a personal computer, a server, a router, a network PC, a peer device, or other common network node, and typically includes many or all of the elements described above relative to the computing device 110, although only a memory storage device 181 has been illustrated in FIG. 2. The network logical connections depicted in FIG. 2 include a local area network (LAN) and a wide area network (WAN), and may also include other networks such as a personal area network (PAN) (not shown). Such networking environments are commonplace in offices, enterprise-wide computer networks, intranets, and the Internet.

When used in a networking environment, the computing system environment 100 is connected to the network 171 through a network interface, such as the network interface 170, the modem 172, or the wireless interface 193. The network may include a LAN network environment, or a WAN network environment, such as the Internet. In a networked environment, program modules depicted relative to the computing device 110, or portions thereof, may be stored in a remote memory storage device. By way of example, and not limitation, FIG. 2 illustrates remote application programs 185 as residing on memory storage device 181. It will be appreciated that the network connections shown are examples and other means of establishing communication link between the computers may be used.

In certain instances, one or more elements of the computing device 110 may be deemed not necessary and omitted. In other instances, one or more other elements may be deemed necessary and added to the computing device.

The environment includes a surface 201, a digital image acquisition device 205 (illustrated as a camera), a plurality of digital images 210, a system 220, and a computing device 292 having a screen 294 visible to a person 296. In an embodiment, two or more of the devices of the environment may communicate wirelessly with each other. In another embodiment, two or more of the devices of the environment may communicate via wired link.

FIGS. 4-5 illustrate an example of the digital images 210. FIG. 4 illustrates an example digital image 210.1 of the plurality of digital images 210. The digital image 210.1 includes perceivable features A-N located in the field of view of the digital image 210.1. The field of view of the digital image 210.1 includes a peripheral border region 210.1B. The peripheral border region may be divided into at least two border region segments for image processing. The at least two border region segments are illustrated as border region segments 211.1 and 211.2. The border segments may abut each other in an embodiment, but are illustrated in FIG. 4 as spaced apart for clarity. Each border region segment has a length (no reference number) and a width 212. The length and/or width of the at least two border segments may or may not be equal. Perceivable features A-J are also illustrated as located within the border region 210.1B of the digital image 210.1

FIG. 5 illustrates an example of digital images 210.1-210.4 of the plurality of digital images 210. Certain perceivable features of perceivable features A-N are also illustrated as lying within the field of view of the digital images 210.2 and 210.4. For example, perceivable features A and B lie with the field of view of the digital image 210.4, and perceivable features D and E lie within the field of view of the digital image 210.2.

FIG. 6 illustrates an example of digital images 210.1-210.8 of the plurality of digital images 210. In this example, the digital images 210.1-210.8 include respective portions of a region of interest 202 of the surface 201. FIG. 6 also illustrates a possible non-imaged portion 218 of a region of interest 202 of the surface 201 as adjacent to digital images 210.3, 210.5, 210.6, and 210.7. FIG. 6 also illustrates digital image 210.6 as including an example perceivable feature W. FIG. 6 also illustrates an embodiment of a spatial relationship or orientation between the perceivable feature W and the possible non-imaged or unimaged portion 218 indicated by a line 216. In an embodiment, the line may be established perpendicular to an edge of the digital image 210.6.

Returning to FIG. 3, the system 220 includes a feature-detection circuit 224. The feature detection circuit is configured to extract at least one respective perceivable feature included in each digital image of the plurality of digital images 210. The each digital image of the plurality of digital images includes a respective portion of a region of interest of a surface a respective portion of the region of interest 202 of the surface 201. An example circuit or system configured to extract at least one respective perceivable feature included in each digital image of the plurality of digital images is provided by Photomodeler and PhotoModeler Scanner products by PhotoModeler® of Vancouver, BC, Canada.

For example, a perceivable feature may include a discernable shape. For example, a perceivable feature may be discernable under natural lighting or under a particular lighting, such as infrared lighting. For example, a perceivable feature may be a static perceivable feature of the surface. For example, where the surface is a surface of a human skin, a perceivable feature may include a hair, wrinkle, surface, color, structure, or texture variation. For example, a perceivable feature may include a color and/or texture change and/or shift in skin or tissue pigments (e.g., melanoma or other tumor borders, burns, scar tissue, necrotic tissue). For example, a perceivable feature may include a perceivable surface vascular feature of a cavity or lumen. For example, a perceivable feature may include a perceivable surface anomaly. For example, a perceivable feature may include a perceivable surface anatomical feature. For example, a perceivable feature may include a perceivable surface vascular feature. For example, a perceivable feature may include a perceivable surface vessel, blood vessel, vascular structure, or a pattern presented by one or more blood vessels of a surface of a human or animal. For example, a perceivable feature may include a perceivable physical structure, void, border, component, tissue, structural feature, or density variation of a surface. For example, a perceivable feature may include a perceivable pattern presented by one or more features. For example, a perceivable feature may include a perceivable fiducial formed by one or more structures, colors, or shapes of a surface. For example, a perceivable feature may include a perceivable relative size or spatial relationship of two or more perceivable physical structures, voids, borders, components, tissues, structural features, or density variations of a surface. For example, a perceivable feature may include a perceivable normal surface feature. For example, a perceivable feature may include a perceivable usual, regular, or typical surface feature. For example, perceivable feature may include a perceivable abnormal surface feature. For example, a perceivable abnormal feature may include perceivable unusual, irregular, or disease state. For example, a perceivable abnormal feature may include perceivable scar tissue, healed lesion, nodule, or encapsulated foreign object. For example, a perceivable feature may include a perceivable feature of a surface that is machine distinguishable from another surface feature. For example, a perceivable feature may include a perceivable surface feature that is machine differentiable from another perceivable surface feature. For example, a computing machine may be able to differentiate between first surface feature and second surface feature, but may not be able to distinguish or discern why they are not the same. For example, where the surface is a surface of an object, the perceivable feature may include a structural element, or a surface variation. For example, a surface color variation may include a red rust spot on a blue car. For example a surface texture variation may include a rust corrosion spot on an otherwise intact surface.

In an embodiment, the perceivable feature includes a human-vision perceivable feature. For example, a human-vision perceivable feature may include a feature that is visible to the naked eye or using natural human vision, including corrective lenses. In an embodiment, the perceivable feature includes an augmented human-vision perceivable feature, such as a feature visible to the naked eye as a result of computer implemented enhancement, or computer augmented vision. In an embodiment, the perceivable feature includes a machine-vision perceivable feature.

Continuing with reference to FIG. 3, the system 220 includes a feature matching circuit 228. The feature matching circuit is configured to determine a substantial correspondence between (x) an extracted perceivable feature included in a border region segment of a selected digital image of the plurality of digital images and (y) an extracted at least one respective perceivable feature included in the each digital image of the plurality of digital images other than the selected digital image (i.e., the plurality digital images minus the selected digital image). For example, if the feature matching circuit determines a substantial correspondence, it may be configured to output a “1”, and if the feature matching circuit does not determine a substantial correspondence, it may be configured to output a “0”. With reference to FIG. 5 for example, if the selected digital image is digital image 210.1, the feature matching circuit would find a substantial correspondence between (x) the perceivable feature A included in a border region segment of the digital image 210.1 and (y) the perceivable feature A included in the digital image 210.4, and would thus output a “1”. The feature matching circuit would not find a substantial correspondence between (x) the perceivable feature A included in the border region segment of the selected digital image 210.1 and (y) any of the other the perceivable features included in the digital images 210.2 and 210.3, and would respectively output a “0” in response to at least one respective perceivable feature included in each digital image of the plurality of digital images 210.2-210.3. For example, with reference to FIG. 5, the feature matching circuit would not find a substantial correspondence between (x) the perceivable feature C included in another border region segment of the selected digital image 210.1 and (y) any of the other the perceivable features included in the digital images 210.2-210.4, and would respectively output a “0” in response to at least one respective perceivable feature included in each digital image of the digital images 210.2-210.4.

Continuing with reference to FIG. 3, the system 220 also includes a data collection circuit 232 configured to gather the determined substantial correspondences for the extracted perceivable feature included in the border region segment of the selected digital image. With reference to the example of FIG. 5 described above, in an embodiment, the data collection circuit would gather the “1” and “0” outputted by the feature matching circuit 228. With reference to the perceivable feature A included in a border region segment of the selected digital image 210.1, the gathered outputs would be a single “1” for the digital image 210.04 and at least one “0” for digital images 210.2 and 210.3, i.e. [1,0,0]. With reference to the perceivable feature C included in a border region segment of the selected digital image 210.1, the gathered outputs would be all “0” for digital images 210.2-210.4, i.e. [0,0,0].

The system 220 also includes a reporting circuit 236. The reporting circuit is configured to output informational data indicative of a possible non-imaged portion of the region of interest 202 of the surface 201. For example, the informational data may be indicative of the possible non-imaged portion 218 of the region of interest 202 of the surface 201 illustrated in FIG. 6. The informational data is responsive to an absence of a determined substantial correspondence between the extracted perceivable feature included in the border region segment of the selected digital image and the extracted at least one respective perceivable feature included in the each digital image of the plurality of digital images other than the selected digital image. With reference to the example of FIG. 5 described above, the data collection circuit 232 would have gathered an absence of a determined substantial correspondence [0,0,0] between the perceivable feature C included in a border region segment of the selected digital image 210.1 and at least one respective perceivable feature included in each digital image of the plurality of digital images 210.2-210.4 other than the selected digital image. In an embodiment, the reporting circuit interprets an absence of a determined substantial correspondence as indicia of a possible non-imaged portion of the region of interest adjacent to the selected digital image.

In an embodiment of the system, each digital image of the plurality of digital images includes an indication of a position or location relative to the region of interest of the surface. In an embodiment, the plurality of digital images respectively includes a plurality of medical images of a portion of a region of interest of a surface of an individual mammal. In an embodiment, each medical image of the plurality of medical images respectively includes a portion of a region of interest of an internal surface of an individual mammalian body part. In an embodiment, the plurality of medical images of an internal surface of an individual mammalian body part was acquired by a body-insertable device. In an embodiment, the plurality of medical images of an internal surface of an individual mammalian body part were acquired by an ex vivo device. In an embodiment, each medical image of the plurality of medical images respectively includes a portion of a region of interest of an external surface of an individual mammal. In an embodiment, each digital image of the plurality of digital images respectively includes a portion of a region of interest of a surface of an object. For example, the object may include the earth or planetary surface, a planetary body, ocean floor, a product, an aircraft, a machine, or a boat. In an embodiment, each digital image of the plurality of digital images includes a respective identifier. For example, an identifier may include an alpha-numeric identifier. In an embodiment, the identifier may be used to identify a digital image adjacent to the possible non-imaged portion of the region of interest. In an embodiment, each digital image of the plurality of digital images includes a respective identifier assigned by a receiver circuit operatively coupled to the system. In an embodiment, each digital image of the plurality of digital images includes a respective identifier assigned by the system. In an embodiment, each digital image of the plurality of digital images includes a respective identifier assigned by the system after receipt by an image receiver circuit. In an embodiment, each digital image of the plurality of digital images includes a respective identifier assigned by another system.

In an embodiment, the feature matching circuit 228 includes a feature matching circuit configured to determine a substantial correspondence between (x) an extracted perceivable feature included in a border region segment of a selected digital image of the plurality of digital images and (y) an extracted at least one respective perceivable feature of a border region segment of the each digital image of the plurality of digital images other than the selected digital image. For example, this may be thought of as edge-feature to edge-feature correspondence or matching. In this embodiment, the feature matching circuit is matching with respect to perceivable features in border region segments of both images. In an embodiment, the feature matching circuit includes a feature matching circuit configured to determine a substantial correspondence between (x) an extracted perceivable feature included in a border region segment of a selected digital image and (y) an extracted at least one respective perceivable feature of a field of view of each digital image of the plurality of digital images other than the selected digital image.

In an embodiment, the system 220 includes an image receiver circuit configured to receive the plurality of digital images. In an embodiment, the system includes a border region detection circuit 226 configured to detect a border region segment of a digital image. In an embodiment, the border region detection circuit includes a border region detection circuit configured to select a length and/or a width parameter of the border regions. The border region detection circuit is also configured to detect a border region segment having the selected length and/or width. For example, the length and/or a width parameter of the border regions may be a percentage of a dimension of the image, or may be a specific length, or a specific number of pixels. For example, the length and/or a width parameter of the border regions may be dynamically varied depending on a result of the feature matching, or depending on speed and processing horsepower available to the system. For example, the length and/or a width parameter of the border regions may be dynamically varied to provide an increased resolution in transition regions. In an embodiment, the border region detection circuit includes a border region detection circuit configured to receive a selected length and/or a width parameter of the border regions. The border region detection circuit is also configured to detect a border region segment of a digital image having the selected length and/or width parameter. In an embodiment, the feature-matching circuit 228 includes a feature-matching circuit configured to determine a substantial correspondence between (x) a perceivable feature included in the detected border region segment of a selected digital image of the plurality of digital images and (y) at least one respective perceivable feature included in each digital image of the plurality of digital images other than the selected digital image.

In an embodiment, the feature-matching circuit 228 includes a feature-matching circuit configured to (i) determine a substantial correspondence between (x) a perceivable feature included in a border region segment of a selected digital image of the plurality of digital images and (y) at least one respective perceivable feature included in each digital image of the plurality of digital images other than the selected digital image. The feature-matching circuit is also configured to (ii) iteratively designate a next perceivable feature included in a next border region segment of the selected digital image. The feature matching circuit is further configured to (iii) initiate a determination of a substantial correspondence of the iteratively designated next perceivable feature included in the next border region segment pursuant to element (i). With reference to FIG. 5 for example, this embodiment will step through at least two iterations by looking for substantial correspondence for perceivable feature A and perceivable feature B. In an embodiment, the data collection circuit 232 includes a data collection circuit configured to gather the determined substantial correspondences for the respective perceivable feature included in the respective border region segments of the selected digital image. In an embodiment, the reporting circuit 236 includes a reporting circuit configured to output informational data indicative of a possible non-imaged portion of the region of interest of the surface. The informational data is responsive to an absence of a determined substantial correspondences between the extracted respective perceivable feature included in the respective border region segments of the at least two border region segments of the selected digital image and the extracted at least one respective perceivable feature included in the each digital image of the plurality of digital images other than the selected digital image.

In an embodiment, the system 220 includes an overlap-analysis circuit 234 configured to generate data indicative of a border region-overlap status of the selected digital image. The data is generated at least partially in response to the determined substantial correspondence between the extracted perceivable feature included in the border region segment of the selected digital image and the extracted at least one respective perceivable feature included in the each digital image of the plurality of digital images other than the selected digital image. For example, a determined absence of a substantial correspondence for perceivable feature in one border region segment of the selected digital image may result in generation of data indicative on a “border region not overlapped” status. With reference to the example of FIG. 5 described above, and in reference to the perceivable feature C included in a border region segment of the selected digital image 210.1; where the gathered determined substantial correspondences for perceivable feature C are all “0” (i.e. [0,0,0]), the overlap-analysis circuit generates data indicative of a “border region not overlapped” status for the border region segment of the digital image 210.1 that includes perceivable feature C. For example, a determined a substantial correspondence for a perceivable feature in one detected border region segment of the selected digital image may result in generation of data indicative of a “border region overlapped” status. With reference to the example of FIG. 5 described above, and in reference to the perceivable feature A included in a border region segment of the selected digital image 210.1; where the gathered determined substantial correspondences for the perceivable feature A include a “1” with respect to digital image 210.4, the overlap-analysis circuit generates data indicative of a “border region overlapped” status for the border region segment of the digital image 210.1 that includes perceivable feature A. In an embodiment, the reporting circuit 236 includes a reporting circuit configured to output informational data indicative of the border region-overlap status of the selected digital image. The informational data is at least partially based on the data indicative of a border region-overlap status of the selected digital image.

FIG. 6 provides a partial illustration of this embodiment. The embodiment provides data indicative of a spatial relationship 216 between the possible non-imaged portion 218 of the region of interest 202 and the perceivable feature included in the border region segment (although FIG. 6 illustrates a situation where the perceivable feature W is not included in the border region). In an embodiment, the overlap-analysis circuit 234 includes an overlap-analysis circuit configured to generate data indicative of a possible non-imaged portion of the region of interest adjacent to the selected digital image; and indicative of a spatial relationship between the possible non-imaged portion of the region of interest and the feature included in a border region segment of the selected digital image. The spatial relationship is indicated by a line anchored by a feature, site, center, or quadrant of the selected digital image. FIG. 6 provides an illustration of this embodiment. The data of this embodiment provides an indication of the spatial relationship 216 between the possible non-imaged portion 218 that is anchored by the perceivable feature W. In an embodiment, the determined spatial relationship is indicated by a line anchored by a feature, site, center, or quadrant of the selected digital image and substantially perpendicular to an edge of the field of view of the digital image.

In an embodiment, the overlap-analysis circuit 234 includes an overlap-analysis circuit configured to generate data indicative of a possible non-imaged portion of the region of interest adjacent to the selected digital image and indicative of a spatial relationship between the possible non-imaged portion of the region of interest and a human-perceivable feature included in the border region segment of the selected digital image.

The system 620 includes 646 an iteration control circuit configured to iteratively designate a next digital image from the plurality of digital images as the selected digital image until each digital image of the plurality of digital images has been designated.

In an embodiment, the coverage-analysis circuit is configured to at least one of determine, classify, find, or locate a possible non-imaged portion of the region of interest. The system includes a reporting circuit 636 configured to output informational data indicative of the possible non-imaged portion of the region of interest.

In an alternative embodiment, the data collection circuit 632 includes a data collection circuit configured to gather and assemble the determined substantial correspondences for the extracted perceivable feature included in the border region segment of the selected digital image. In an alternative embodiment, the data collection circuit includes a data collection circuit configured to gather the determined substantial correspondences for a respective perceivable feature included in each respective border region segment of the selected digital image.

In an alternative embodiment, the coverage-analysis circuit 648 includes a coverage-analysis circuit configured to identify a particular portion of the region of interest of a surface as likely not included in the plurality of digital images (hereafter “possible non-imaged portion of the region of interest”) and to identify at least one digital image of the plurality of digital images (hereafter “signpost digital image”) as spatially proximate to the possible non-imaged portion of the region of interest. The identification of the possible non-imaged portion of the region of interest and the identification of the signpost digital image is at least partially based on the omitted-coverage list. With reference to the example of FIG. 6 described above, the coverage-analysis circuit may identify for example at least one of images 210.3, 210.5, 210.6, and 210.7 as the signpost digital image spatially proximate to the possible non-imaged portion of the region of interest 218. In an alternative embodiment, for example, if the digital image 210.8 included a readily perceivable feature such as a mole, the coverage-analysis circuit may identify the digital image 210.8 as the signpost digital image adjacent to the possible non-imaged portion of the region of interest 218 even though the digital image 210.8 is not immediately adjacent.

In an alternative embodiment, the coverage-analysis circuit 648 includes a coverage-analysis circuit configured to identify a particular portion of the region of interest of a surface as likely not included in the plurality of digital images (hereafter “possible non-imaged portion of the region of interest”). The identification of the possible non-imaged portion of the region of interest is at least partially based on application of a filter or a template to the omitted-coverage list. For example, the filter may include a threshold requirement that a certain minimum number of adjacent border region segments of the selected digital image have a “likely not overlapped” determined border region-overlap status before identification of a particular portion of the region of interest of a surface as likely not included in the plurality of digital images:

FIG. 13 partially illustrates an application of an alternative embodiment of the coverage-analysis circuit 648 to the plurality of digital images 210 previously illustrated in FIG. 6. In the alternative embodiment, the coverage-analysis circuit 648 includes a coverage-analysis circuit configured to (i) identify a particular portion 218 of the region of interest 202 of a surface 201 as likely not included in the plurality of digital images (hereafter “possible non-imaged portion of the region of interest”). The identification of the possible non-imaged portion of the region of interest is at least partially based on the omitted-coverage list. The coverage-analysis circuit is also configured to (ii) identify at least three digital images of the plurality of digital images immediately adjacent to the possible non-imaged portion of the region of interest. The identification of the at least three digital images is at least partially based on the omitted-coverage list. In a first example, a first set of identified at least three digital images includes digital images 210.3, 210.5, 210.6, and 210.7. The coverage-analysis circuit is also configured to (iii) define a simple closed curve formed by linking at least one detected border region segment of each of the at least three identified digital images, wherein the border region segments each have an overlap status of “likely not overlapped”. For example, a simple closed curve, sometimes known as a Jordan curve, includes a non-self intersecting closed curve, i.e., a connected curve that does not cross itself and ends at the same point where it begins. A first simple closed curve 652 is formed by linking at least one detected border region segment of each of the at least three identified digital images, wherein the border region segments each have an overlap status of “likely not overlapped.” The coverage-analysis circuit is also configured to (iv) determine whether the possible non-imaged portion of the region of interest lies substantially inside or substantially outside of the region of interest. The determination is at least partially based on the positions of the identified at least three digital images relative to the closed curve. FIG. 13 illustrates the positions of the first set of the identified at least three digital images (210.3, 210.5, 210.6, and 210.7) as substantially outside of the first closed curve 652. As a result, the coverage-analysis circuit would determine that the first possible non-imaged portion 218 of the surface lies inside of the region of interest. In a second example, a second possible non-imaged portion 219 of the surface is identified. A second set of identified at least three digital images includes digital images 210.1, 210.2, and 210.4. A second simple closed curve 654 is formed by linking at least one detected border region segment of each of the second set of at least three identified digital images, wherein the border region segments each have an overlap status of “likely not overlapped.” FIG. 13 illustrates the positions of the second set of identified at least three digital images (210.1, 210.2, and 210.4) as substantially inside the second closed curve 654. As a result, the coverage-analysis circuit would determine that the second possible non-imaged portion 219 of the surface lies outside of the region of interest. Continuing with reference to FIG. 12, in an embodiment, the reporting circuit 636 includes a reporting circuit configured to output informational data indicative of the identified possible non-imaged portion of the region of interest and indicative of the determination whether the possible non-imaged portion of the region of interest lies inside or outside of the region of interest.

FIG. 13 partially illustrates another alternative embodiment of the coverage-analysis circuit 648. In an alternative embodiment, the coverage-analysis circuit includes a coverage-analysis circuit configured to (i) tentatively identify a particular portion of the region of interest 202 of the surface 201 as likely not included in the plurality of digital images 210 (hereafter “tentative non-imaged portion”). The “tentative non-imaged portion” is identified at least partially based on an analysis of the omitted-coverage list. The coverage-analysis circuit is also configured to (ii) determine if the “tentative non-imaged portion” likely includes an outer periphery portion of the region of interest included in the plurality of digital images. For example, a first “tentative non-imaged portion” of this alternative embodiment may be illustrated by the first non-imaged portion 218 and a second “tentative non-imaged portion” of this alternative embodiment may be illustrated by the second non-imaged portion 219. Any technique known to those of skill in the art may be used to make this determination. For example, the coverage-analysis circuit may use the previously described technique of defining a simple closed curve linking at least one border region segment of each of at least three identified digital images adjacent to a “tentative non-imaged portion of the region of interest” and determining whether the “tentative non-imaged portion of the region of interest” lies inside or outside of the region of interest. As described above, the first “tentative non-imaged portion” of this alternative embodiment by the first non-imaged portion 218 would be determined as “likely does not include an outer periphery of the region of interest included in the plurality of digital images.” Also as described above, the second “tentative non-imaged portion” of this alternative embodiment illustrated by the second non-imaged portion 219 would be determined a “likely does include an outer periphery of the region of interest included in the plurality of digital images.”

In this embodiment, the coverage-analysis circuit 648 is also configured (iii) if the identified “tentative non-imaged portion” likely does not include an outer periphery of the region of interest 202 included in the plurality of digital images 210, to classify the “tentative non-imaged portion” as a “possible non-imaged portion of the region of interest.” Continuing with the above example, since the first “tentative non-imaged portion,” illustrated by the first possible non-imaged portion 218, would be determined as likely does not include an outer periphery of the region of interest included in the plurality of digital images, the coverage-analysis circuit will classify it as a “possible non-imaged portion of the region of interest.” The reporting circuit 636 will output informational data indicative of the possible non-imaged portion 218 of the region of interest. Continuing with the above example, since the second “tentative non-imaged portion,” illustrated by the second possible non-imaged portion 219, would be determined as likely does include an outer periphery of the region of interest included in the plurality of digital images, the coverage-analysis circuit will not classify it as a “possible non-imaged portion of the region of interest.” As a result, the reporting circuit will not output informational data indicative of the possible non-imaged portion of the region of interest 219. An advantage of this embodiment is that the reporting circuit will not output informational data indicative of “possible non-imaged portions of the region of interest” lying on the outer periphery of the plurality of digital images. Since the plurality of digital images only describe a part of the surface 201, these unbounded regions may be beyond the desired region of interest of the surface and are in effect winnowed out of the reporting.

Continuing with reference to FIG. 12, in an embodiment, the reporting circuit 636 includes a reporting circuit configured to output a rendering of the informational data in a form facilitating a human-perceivable representation of the informational data. For example, the reporting circuit may be configured to output a rendering of the informational data optimized in a form facilitating a human-perceivable representation of the informational data on a portable display, such as a display device associated with the communication device 642, or the screen 294 associated with the computing device 292. For example, the reporting circuit may be configured to output the informational data in a format facilitating a human-viewable representation of the informational data.

All references cited herein are hereby incorporated by reference in their entirety or to the extent their subject matter is not otherwise inconsistent herewith.

In some embodiments, “configured” includes at least one of designed, set up, shaped, implemented, constructed, or adapted for at least one of a particular purpose, application, or function.

It will be understood that, in general, terms used herein, and especially in the appended claims, are generally intended as “open” terms. For example, the term “including” should be interpreted as “including but not limited to.” For example, the term “having” should be interpreted as “having at least.” For example, the term “has” should be interpreted as “having at least.” For example, the term “includes” should be interpreted as “includes but is not limited to,” etc. It will be further understood that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of introductory phrases such as “at least one” or “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a receiver” should typically be interpreted to mean “at least one receiver”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, it will be recognized that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “at least two chambers,” or “a plurality of chambers,” without other modifiers, typically means at least two chambers).

In those instances where a phrase such as “at least one of A, B, and C,” “at least one of A, B, or C,” or “an [item] selected from the group consisting of A, B, and C,” is used, in general such a construction is intended to be disjunctive (e.g., any of these phrases would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, or A, B, and C together, and may further include more than one of A, B, or C, such as A₁, A₂, and C together, A, B₁, B₂, C₁, and C₂ together, or B₁ and B₂ together). It will be further understood that virtually any disjunctive word or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”

The herein described aspects depict different components contained within, or connected with, different other components. It is to be understood that such depicted architectures are merely examples, and that in fact many other architectures can be implemented which achieve the same functionality. In a conceptual sense, any arrangement of components to achieve the same functionality is effectively “associated” such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality can be seen as “associated with” each other such that the desired functionality is achieved, irrespective of architectures or intermedial components. Likewise, any two components so associated can also be viewed as being “operably connected,” or “operably coupled,” to each other to achieve the desired functionality. Any two components capable of being so associated can also be viewed as being “operably couplable” to each other to achieve the desired functionality. Specific examples of operably couplable include but are not limited to physically mateable or physically interacting components or wirelessly interactable or wirelessly interacting components.

With respect to the appended claims the recited operations therein may generally be performed in any order. Also, although various operational flows are presented in a sequence(s), it should be understood that the various operations may be performed in other orders than those which are illustrated, or may be performed concurrently. Examples of such alternate orderings may include overlapping, interleaved, interrupted, reordered, incremental, preparatory, supplemental, simultaneous, reverse, or other variant orderings, unless context dictates otherwise. Use of “Start,” “End,” “Stop,” or the like blocks in the block diagrams is not intended to indicate a limitation on the beginning or end of any operations or functions in the diagram. Such flowcharts or diagrams may be incorporated into other flowcharts or diagrams where additional functions are performed before or after the functions shown in the diagrams of this application. Furthermore, terms like “responsive to,” “related to,” or other past-tense adjectives are generally not intended to exclude such variants, unless context dictates otherwise.
